Kev Tswj Xyuas Qhov Ntsuas NaOH Hauv Kev Tsim Khoom Siv Organic Intermediate
Hauv kev tsim cov organic intermediate synthesis, kev tswj hwm qhov tseeb ntawm sodium hydroxide (NaOH) concentration yog qhov tseem ceeb ntawm cov khoom zoo, kev ua haujlwm zoo, thiab kev ua lag luam. Kev siv NaOH hauv kev tsim cov organic intermediates xws li cov ntsev phenoxide thiab cov ntsev alkoxide ua lub luag haujlwm tseem ceeb hauv kev tsim cov xim, tshuaj, thiab cov ntaub ntawv polymeric, vim tias cov intermediates no ua lub hauv paus tseem ceeb rau kev tsim cov organic compounds muaj nqis siab.
Rau kev tsim cov phenoxide thiab alkoxide ntsev, lub tshuab ua haujlwm ntawm NaOH yog raws li nws cov alkalinity muaj zog. Los ntawm inline ultrasonic sensing technology, NaOH-mediated synthesis txheej txheem tuaj yeem saib xyuas tau tiag tiag ntawm ntau theem.
Qhov Nyuaj Hauv Kev Tswj Xyuas NaOH Concentration Rau Organic Intermediate Synthesis
Kev tswj hwm qhov concentration ntawm NaOH hauv cov organic intermediate synthesis ua rau muaj teeb meem tseem ceeb uas cuam tshuam nrog nws cov yam ntxwv tshuaj lom neeg thiab cov txheej txheem dynamics. Nws qhov solubility tsawg hauv cov organic solvents ua rau muaj nag, thaum kev sib xyaw tsis zoo hauv cov reactors loj tsim cov concentration gradients - ua rau tsis sib xws phenoxide / alkoxide tsim.

Cov Ntsiab Lus Teeb Tsa Hauv Online Density Meter Hauv NaOH Concentration Control
Cov ntsuas qhov ceev online feem ntau raug teeb tsa rau hauv 4 qhov txuas tseem ceeb ntawm cov txheej txheem, tsom mus rau kev saib xyuas qhov concentration ntawm NaOH cov kua kom ntseeg tau tias cov txheej txheem ruaj khov:
Kev Npaj Khoom Siv Raw NaOH
Thaum npaj cov khoom NaOH khov rau hauv cov tshuaj dilute uas xav tau,sodium hydroxide concentrationlub 'meter'yog mounted rau ntawmtawmthiab ntawm mixinglub tank. Nws hloov qhov ceev uas ntsuas tau mus rau qhov concentration hauv lub sijhawm tiag tiag, zam kev ua yuam kev los ntawm kev sib sau ua ke thiab ua kom muaj qhov tseeb ntawm cov khoom noj khoom haus.
Kev kho ua ntej pub tshuaj tiv thaiv
Ua ntej NaOH kua raug pumped rau hauv lub reactor, lubsodium hydroxide concentration sensortau teeb tsa rau ntawm cov kav dej NaOH. Nws xyuas kom meej tias qhov concentration ua raws li qhov yuav tsum tau ua kom tsis txhob muaj cov tshuaj lom neeg txaus los yog cov tshuaj tiv thaiv sab nraud uas tshwm sim los ntawm cov concentration tsis raws li qhov yuav tsum tau ua.
Kev Soj Ntsuam Xyuas Cov Tshuaj Tiv Thaiv Hauv Cov Txheej Txheem
Rau cov tshuaj tiv thaiv uas NaOH concentration hloov pauv tas li, lub ntsuas qhov ceev yuav raug teeb tsa rau ntawm lub reactor lub raj xa dej sab hauv lossis lub raj xa dej kuaj qhov tawm. Nws taug qab cov kev hloov pauv ntawm cov concentration tam sim ntawd los coj NaOH ua kom raws sijhawm, zam kev hydrolysis lossis cov tshuaj tiv thaiv tsis tiav.
Kev Rov Qab Los Tom Qab Kev Ua Tshuaj Tiv Thaiv/Kev Ntxuav
Yog tias NaOH uas tsis tau ua haujlwm raug siv rov ua dua lossis siv rau kev ntxuav khoom, lub ntsuas qhov ceev yuav raug ntsia rau ntawm qhov nkag / qhov tawm ntawm lub tank khaws cov kua rov qab. Nws saib xyuas qhov concentration ntawm NaOH rov ua dua tshiab, txiav txim siab seb puas yuav dilute lossis ntxiv, thiab xyuas kom meej tias qhov concentration ntawm cov kua ntxuav ua tau raws li qhov yuav tsum tau ua kom huv (piv txwv li, tiv thaiv kom tsis txhob muaj NaOH seem ntau dhau hauv cov khoom nruab nrab).
Kawm Txog Ntau Cov Ntsuas Qhov Ceev
Cov txiaj ntsig los ntawm Sodium Hydroxide Concentration Meter
Lub ntsuas sodium hydroxide (NaOH) concentration muab qhov tseem ceeb rau cov organic intermediate synthesis los ntawm kev daws cov teeb meem tseem ceeb ntawm kev tswj concentration, nrog rau cov txiaj ntsig tseem ceeb raws li hauv qab no:
●Kuvtua rau muaj kev soj ntsuam tiag tiag, meej, hloov cov txheej txheem qeeb, offline xws li titration. Los ntawm kev hloov qhov ceev mus rau qhov concentration tam sim ntawd, nws ua kom NaOH nyob hauv qhov ntau thiab tsawg, zam kev noj tshuaj tsawg dhau lossis noj tshuaj ntau dhau.
●Kuvt ua rau cov txheej txheem ruaj khov thiab cov khoom sib xws. Los ntawm kev tiv thaiv kev siv NaOH ntau dhau thiab ua kom rov ua dua tshiab ntawm NaOH uas tsis tau ua haujlwm zoo, nws txo cov nqi khoom siv thiab txo cov nra hnyav ntawm kev kho cov khib nyiab.
●It txhim kho kev nyab xeeb thiab kev ua raws li txoj cai. Cov lus ceeb toom tiag tiag rau cov concentration tsis zoo txo qhov kev pheej hmoo ntawm kev xeb ntawm reactor lossis exothermic runaway. Tsis tas li ntawd, nws cov ntaub ntawv sau ua haujlwm ua tau raws li cov kev cai lij choj rau kev taug qab rau cov lag luam xws li tshuaj, ua kom yooj yim rau cov txheej txheem kev tshuaj xyuas.
